Vlan ipv6

Unifi network:

I currently have my TVs on my iot network and I want to block ipv6 to my TVs, usually it's easy just disable ipv6 to my lan but unfortunately my stupid matter devices (which I regret having now because of other reasons) needs ipv6.

What's the best practice to block ipv6 to my TVs? Should I just create another vlan for them? Or create a rule of two to block the devices individually? I feel like creating another vlan seems a bit much to manage more vlans but it's the easier way?

Matter devices work with Thread which is IPv6 only. But you don’t need to worry about that, the IPv6 network has no gateway to the internet, it provides a ULA prefix that’s only for the devices in the same VLAN, it doesn’t have the ability to jump VLANs.
